Someone up thread mentioned testing of the polio vaccine. The Salk vaccine was given an early release. There were loud complaints about the design of the testing of the vaccine. And because it was so new, there were no longitudinal data studies as follow ups with the recipients. (Now we all know about Post Polio Syndrome.) And apparently many of our parents thought that the vaccination gave their children a chance of a life outside an iron long or crippled. Where I grew up not far from Lkwd, 6 kids had polio, one died, the rest were physically crippled for life. (The March of Dimes has a good history of polio and the vaccines.)
